How much we talking for a forged rebuild?

I actually get an average of 70mpg coming into work, and about 55mpg or so on the way home. Not sure if it's a case of going downhill to and uphill from work, or if I'm taking my time more on the way in and speeding up to get away at the end of shift  . The 1.9 105bhp with the chip makes it very frugal indeed, cruise control also helps. LOL, IMO ECO=SH*T!!!

Really sorry to hear about this Phil,this just makes me wonder whether to get rid as im about to start using the car daily or get a total rebuild and harden her up,very sorry mate, but it sounds like you have taken it on the chin and kept your head up,good for you mate.

He's also kindly offered to refund my tuning fees, which was kind as he didn't have to do that at all. I'd take from this that if anyone is going to remap the MPS, then you can't go far wrong by getting the services of Alex onboard for peace of mind with his safety on the vvt side of things. Quote: Hi Phil and I am very sorry to hear about these misfortunes. Did the VVT actuator give in right at the same time as the conrod let go? Unfortunately there are many stories with the MPS cars blowing up. This is especially true of the MPS6 since it generates a higher load on the engine being AWD and heavier - even ones that are completely stock. I have myself done in-depth analysis of what goes on with these cars and it appears that detonation kills the engines slowly, the rods bend, and eventually give up. Mazda has calibrated these cars very aggressively in terms of VVT from the factory (which causes a high dynamic compression ratio) and on the highway it is common for the car to stumble when you get on the throttle after a longer cruise. Have you noticed this with yours? Also a tell-tale sign of the engine starting to let go are vibrations in the clutch pedal. Did you experience these? The root cause is aggressive VVT timing and very hot combustion. It causes some severe detonation that over time weakens the conrods and they let go. This is of course unless something else happened at the shop. Starting with 2010, the VVT timing was revamped from the factory and new pistons fitted to the DISI engine and the cars no longer blow up. On my own MPS3 I had the same issues and have resolved them with a reduction in VVT timing - and since then I have not had the car stumble once. All the MPS cars I tune I make these changes to keep them safe but it is sometimes too late as the damage is done over time. There are many resources on blown speeds here: http://www.mazdaspeedforums.org/forum/f10/mazdaspeed-2-3l-disi-turbo-blown-engine-resource-thread-6113/ I can refund you the price for the tune to help things out a little. Thank you, Alex This clears up the logic of how valve timing causes issues, thanks. Not enough cam overlap & too much Dynamic CR, leading to high combustion temps thus pre-det knock. Rods don't like that much. Running E90 or higher octane fuel would help, but adds to running costs.

On the other hand, only 23 cars listed - only 1 Speed6, I know it shouldn't happen at all but I'm trying to put the numbers into perspective and KEEP CALM.

Same as azzaboy
Though it's a fantastic car so may fork out the £2200 ish to have a rebuild as I don't want to change cars, I'd like to keep this for a good 3-5 years.

I'd like to add my condolences too Phil...absolute nightmare I blew an engine on my old Almera GTI a few years back on the motorway but then that was a 97 reg and not exactly a pristine example...unbeknown to me there were flames under my car as I sat on the hard shoulder and a geyser in a white van pulled up in front and told me to get out of the car...he'd already called the fire brigade and two rigs turned up together with the break down truck I'd called...Was like the end scene from a Die Hard film...  That said it's a bit of a sobering thought that these 'modern' and 'reliable' cars we drive can come to such a catastrophic end...and more worrying that standard examples can go the same way as lightly or more heavily modded ones. I was very perturbed to read from the fella that did your map that the things to look out for were 'the car stumbling on the MWay when you get on the throttle' as I swear that's what my MK1 did on the way home yesterday. I was in 6th and just put my foot down and WTF?...the car seemed to pick itself up and jerk sideways a bit... Now I have no mods whatsoever except for Versatune high load tune...so the question is do I revert back to the car's standard tune for safety's sake? Taking the car to Mazda next week for one of these free health checks but I'm going to insist they take a look at the rods etc and see if they can tell if there is a problem. Don't know whether to take versatune off before taking it there as they may cause a prob if they whack in their OBII cable for checking any glitches. The car seems a bit sluggish at the mo too and the steering is definitely more 'loose' ...I figured that might be me needing new tyres as remember having the same feeling last year before I bought new rubber...at least I hope it's that and not more indications of rods about to snap. Does anybody have a rough idea how much it would cost for having new forged rods to replace originals?

Dolf77 - I would start by reverting to OEM map and taking it from there. The stumbling could be other things including the O2 sensor. Mind you that generates serious stumbling, in my experience. I think you would need to replace all the innards not just the con rods. They break because they are the weakest link.
